Master (Spark Plasma) Sintering Curve of UO2 and UO2-10 Vol. % Mo Fuel Material
Bibliographic record
Abstract
Abstract UO2-molybdenum (Mo) composites are being considered for accident tolerant fuel (ATF) applications in commercial nuclear reactors. In this study, UO2-10 vol. % Mo was fabricated using spark plasma sintering (SPS), where the particle size of Mo was varied between 30 nm, 60 nm, 100 nm, and 150 μm, to study its effect on the densification of the UO2-10 vol. % Mo composite. A decrease in Mo particle size was identified to cause a shift in densification peaks in UO2-Mo toward higher temperature, due to the Mo particles coating the bigger UO2 particles. The in situ ram displacement data was used to construct a master sintering curve (MSC), which was validated using additional SPS trials. The accuracy of the MSC was measured by the standard deviation between prediction and experimentally observed data, which varied from 0.7% to 4.8%.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
